8 GB DDR4 3200 UDIMM for MSI B550M PRO-VDH

This 8 GB DDR4 module runs at 3200 MT/s with CL22 latency and 1.2 V operation. It is validated for the MSI B550M PRO-VDH motherboard and targets users who want a straightforward capacity increase for everyday desktop workloads. The single-rank 1Rx8 organisation keeps compatibility simple on two-slot boards. Non-ECC unbuffered design matches standard consumer platform requirements.

Tool-free slot installation with keyed alignment

The 288-pin UDIMM clicks into the DDR4 slot using the motherboard's retention clips. No heat spreader means the module sits low, reducing interference with larger CPU coolers. Common issues include forgetting to seat both ends until the clips snap, or mixing speeds that force the system to downclock. Always power off and disconnect the mains before handling the module.

Verify DDR4 slot count and maximum supported speed

Check that the board has a free DDR4 UDIMM slot and that the BIOS recognises 3200 MT/s modules. The MSI B550M PRO-VDH supports dual-channel architecture, so adding a second identical stick later will enable dual-channel bandwidth. Confirm the current memory configuration in BIOS or the operating system to avoid exceeding the platform's total capacity limit.

Questions about this item

How do I confirm the module is running at DDR4 3200 CL22 1.2V after installing it in my MSI B550M PRO-VDH?

Enter the BIOS or use a tool such as CPU-Z to verify the memory frequency reads 3200 MT/s, the CAS latency shows 22 and the voltage is set to 1.20 V.

What comes in the package and do I need any extra parts for installation?

The box contains one 8 GB 288-pin UDIMM; no heat spreader, cables or tools are included and none are required for a standard desktop DIMM slot.

Should I choose the 8 GB single-rank 1Rx8 version or look for a different capacity?

This specific kit is an 8 GB 1Rx8 module rated DDR4 3200 CL22 1.2 V; select it when you need a single 8 GB stick for the MSI B550M PRO-VDH.
